20100290264 | OPTOELECTRONIC MEMORY DEVICES - A structure. The structure includes a substrate, a resistive/reflective region on the substrate, and a light source/light detecting and/or a sens-amp circuit configured to ascertain a reflectance and/or resistance change in the resistive/reflective region. The resistive/reflective region includes a material having a characteristic of the material's reflectance and/or resistance being changed due to a phase change in the material. The resistive/reflective region is configured to respond, to an electric current through the resistive/reflective region and/or a laser beam projected on the resistive/reflective region, by the phase change in the material which causes a reflectance and/resistance change in the resistive/reflective region from a first reflectance and/or resistance value to a second reflectance and/or resistance value different from the first reflectance and/or resistance value. | 11-18-2010 |

20130258765 | METHOD OF CHANGING REFLECTANCE OR RESISTANCE OF A REGION IN AN OPTOELECTRONIC MEMORY DEVICE - A method for changing reflectance or resistance of a region in an optoelectronic memory device. Changing the reflectance of the region includes sending an electric current through the region to cause a reflectance change in the region. Changing the resistance of the region includes: projecting a laser beam at a first beam intensity on the region, resulting in the region changing from a first to a second different resistance value; electrically reading the second resistance value during which an optical signal carried by the laser beam has a first digital value; after electrically reading the second resistance value, the laser beam is projected at a second beam intensity on the region resulting in the region changing from the second to the first resistance value; and electrically reading the first resistance value of the region while the laser beam is being projected on the region at the second beam intensity. | 10-03-2013 |
